Letters Patent No. 112,358, dated March 7, 1871. Rj- IMPROVEMENT IN APPARATUS FCR BURNING HYDROC-ARBON OILS.

The Schedule referred to in these Letters Patent and making part of the same.

.'ZoL all whom it may concern:

'Be it known that I, J AMES R. LEE, of Grass Valley, county of Nevada, `vented an Improvementin the (lombustionoi' Hydrocarbon Oils; and I do hereby declare the following to enable any person skilled i-n the art or vscience to which it most nearly appertains to makeand use my said invention or improvement without further invention or experiment.

Y The object of my invention is to provide a devicel `by which a more perfect combustion of hydrocarbon oils is secured when they are employed in the furnaces of steam-boilers,'and also the employment and utilization' of exhaust fstearnwthin. .thefnrnaceto assist and promote suoli conilonstiii.,` Y.

It consists in lthe use offa series of shallow troughs, placed preferably in a transverse position in the furdepth, and is burned from them.

, 'Into these troughsethe oilfis .fed so' as to have litt-le A pipe or series `of pipesarranged aroundthe .inte-2 rior of the furnace receivesa'portionoi' theexhaust steaimhnd throws it into the iii-'e in fire-jets, soas to mingle with it asthoroughly as possible, and by its decomposition tosupplyoxygen. A

` A branch of the exhaust-pipe is carried in'behind the bridge-wall, and is so perforated that the jets of steam issuing from it servetoincrease'the draught, as maybe desired. j

Referring to the accompanying drawing for a more complete explanation oi' my invention-` A is a boiler set in brick-work B, having the ordi- W'ithin this lire-box or furnace a number of shallow iron pans, D, i's placed transversely, being introducedor removed at pleasure through a side door, E.

- .The sides of these 'pans are iliade quite iiaring, or

so as `to ,stand .at a considerable angle with the bottom, this construction allowing the ilame free access,

so that the residual tar can also be burned.

The petroleum or other hydrocarbon oil -to be used isied into the pansthrough pipes a, and is intended to stand at a small depth, about one-fourth oi' un inch.

In order to regulate this the pipes a' are'connectedVv themselves placed with a series oi' boxes, F, which are withina largerbox or tank. G.

. The inner` edges of the boxes F are made of such a height'that any surplus oil beyond what is necessaryli'or thepaus will llow overthe edge into the tan k G, from which it flows State oi' California, have in accompanying drawing are sufficient This latter tank may be placed at any convenient point, and the oil may be pumped from it into a tank, 1..' t g l From the tank the oil ilows by supply-pipes J to the boxes F, and is regulated by cocks b.

'lhe pipes a are so constructed with the boxes'F that they can be easily uncoupled, and the pans D can be easily removed for repairs or cleaning.

Any number oi' pans can be used, and the re isregulated by shutting oi the oil from one or more. If' found desirable, one or morev rows of pieces of charcoal, set ou end, may be employed to give a greater lmrningsurface, serving as wicks tol draw the oil up by capillary attraction.

In order to increase the combustion and give a more` `intense heat, as well as to economize steam,v

as to Adirect the steam backward, and thus, by cre-Y ating a partial vacuum, to cause the flame to tend in that direction.

L The amount of' steam admitted to this part of' the furnace can be regulated by a stop-cock, L.

`The remainder of the exhaust steam, or such portion of itas may be desired, is carried into a pipe, M, just behind the bridge-wall, and' issues through perforations into that part of the furnace, being directed toward the back part, and thus increasing the draught, as well as employing more oxygen and hydrogen to unite with any unconsu'med carbon dame which may pass over, the wall.

Ii found necessary the draught may be increased,

when the iire is first started, by introducing air to the pipe K by bellows or other suitable device. 4 The use vof steam as described above, although necessary to the perfect combuston -oi hydrocarbon oils, is not confined to those furnaces, as it may be used with good effect in coal and other furnaces.
